What people actually got
Last observed Winter 20265 terms observed
This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.
Per-term figures stay hidden until each term clears five contributors. 5 observations can support one honest number; they cannot support 5.

Counts, not a library. Pyko does not host or distribute course files, and this page is not an offer to supply one — the archive is what lets these pages describe how a course is assessed, which matters most where no syllabus has been verified.

What this opens up
16 courses list CSC263H1 as a prerequisiteThe other 7 have no page yet. Listing a course here means it names CSC263H1 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what CSC263H1 makes available, not what it alone guarantees.
